This invention relates to new and useful instance be thoroughl purified,and in an-l other instance, a mo 'cation of the main idea, be thoroughlypurified and dried. In both instances, the air is also cooled to arela-- tively high degree, so as to maintain the.

uil

interior of the ding in a relatively cool state during the warm weather.

An important object of the invention is to provide a Ventilatingapparatus for use in the home or for use, on a sli htly larger scale,within a theatre, oflice bui ding or the like, of a generallyinexpensive nature, and that is highly elicient in attaining the desiredresults.

In the drawings wherein there is disclosed two embodiments of thepresent invention:

Figure 1 is a detailed longitudinal sectional viewthrou h one type ofthe invention that is prefera ly used in the home.

Figure 2 is a horizontal section taken at right angles to Figure 1.

Figure 3 is an enlarged fragmentary longitudinal section through theabsorbent disk carrying unit that forms an essential feature of theinvention.

Figure 4 is a detailed longitudinal section through a Ventilatingapparatus constructed in accordance with the present invention, and of atype preferably employed on a large scale, that is, within theatres,oiice buildings and the like.

Figure 5 is a view partially in end elevation and partially in crosssection through that type of the apparatus disclosed in Figure 4, and

Figure 6 is an enlarged fragmentary section through the air dryingchamber of this type o the invention.

First having reference to Figures 1, 2 and 3, the form of the inventionillustrated therein consists o a housing 5 of suitable material,

the front and rear wall of which are provided with relatively large'circular openings 6-6, while the top thereof is provided with a hingelid 7, in order that access may be had to the housing. Arranged withinthe bottom of this housing is a water pan 8 at one end of which isarranged a water tank 9, having a suitable filler neck 10 projectingthrough an opening in the hinged lid of the housin as illustrated inFigure 2. The lower end o this tank is equipped with a discharge nozzle11, the outlet .end of which is arranged within the water pan 8, so thata steady flow of water will be introduced into the pan for maintaining apermanent level thereof, as illustrated in Figure'2.

Within the housing 5 between the tank 9 and the opposite end wallthereof are a pair of spaced shaft supporting brackets 12-12 adapted toloosely support the opposite ends of a horizontal shaft 13. Mounted uponthis shaft 13 at spaced points are disks of absorbent material such asblotting paper 14 maintained in spaced relation by suitable spacingcollars 15. Intermediate the disks of absorbent material are disks ofwire mesh s`creening 16 which are also arranged upon the shaft andfunction as a supporting means to prevent excessive sagging or lateralbending of the absorbent discs'when the same are saturated with water.

The diameter of the disks 14 and 16 are such that they will alwaysengage at their lower ends within the water within the pan 8, asillustrated in Figures 1 and 2. Furthermore, these disks are free to'rotate upon the shaft 13 as suggested by the curved arrow in Figure 1.

Arranged at the backside' of the housing 7 is a fan housin 17, the fanblade unit 18 of which is located directly in back of the circularopening in the rear wall of the housing, so that the air being dischar dforwardly by the fan will pass through t e housinV 5, as disclosed bythe horizontal arrows in igure 4. During the passage of the air throughthe housing 5, it will come into contact with the absorbent disks 14, aswell as the screen wire disks 16. `This will thoroughly remove from theair all impurities, and will at the same time cool the same to aconsiderable degree.

In the form of the invention illustrated in Figures 4, 5 and 6, the samegeneral construction is present. In this instance however, the housing 5is of considerable length, and is provided throughout its length with aseries of vertical partitions 6, the lower edges of which are spacedfrom the bottom wall of the housin and which are provided with largecircuir openings 6a. At the opposite ends of this housing 5 arerelatively narrow compartments or chambers 17 '-17' The variouscompartments of the housing 5', as well as the outer endmost chamber 17are provided with hinged lids as clearly illustratedl so that access maybe had therein.

Within the bottom of the housing 5' is ar' ranged a water pan 8', whilearranged transversely within each of the compartments of the housing arescreen and absorbent disk material units designated in their entirety bythe reference characters 14'. These units are of identical constructionas the unit in the previously described form of the invention, and adetailed description thereof is not believed necessary.

Within the outer end compartment 17 are a pluralit of spaced bafiielates 19 alternate ones of W ich are in space relation with the upperand lower walls of the chamber, as disclosed in Figure 4. These bailleplates are covered by a suitable moisture gathering material 20, asdisclosed in Figure 6, while within the bottom of this chamber is amoisture collecting pan 21.

Within the rear end chamber 17 of the device is located a suitable fanor blowerl 22 projecting air'through the compartments of the housing, aswell as through the moisture removing chamber or compartment 17', andobviously during the passage of the air through the compartments of themain housing, the air will be thoroughly purified andcooled whilewhenpassing through the moisture absorbing chamber, all moisture within theair will be collected, so that the air when finally leaving theapparatus will be of a thoroughly cleaned, cooled and dried nature.

In view of the foregoing description when considered in conjunction withthe accompanying drawings, it will be a parent\that Iv have provided a.novel, simp e and highly eiicient Ventilating apparatus, in each mod1`fication of t-he invention, and'even though I have herein shown anddescribed the two' modifications as consisting of certain detailedstructural features, it is nevertheless to be understood that' somechanges may be made therein, without affecting the spirit and scope ofthe appended claim. l Having thus described my invention, what 1 claimas new, and desire to secure by Letters-Patent, is:

In a Ventilating apparatus of the character described, a housing havingair passages at its opposite ends, a fan at one end thereof for drivingair througlh the housin a transversely extending s aft mounted orrotation in the housin a series of absorbent discs mounted on t e shaftin spaced relation, means for supplying water to the absorbent discs anda series of. foramnous discs mounted on the shaft intermediate theabsorbent discs and in spaced relation thereto said foraminous discsconstituting lateral supporting means for preventing excessive saggin orbending of the absorbent discs after t e latter are saturated withwater.

In testimony whereof I aiiix my signature.

CHARLES FERGUSON.
